ABSTRACT:
In a data transmission system, apparatus for converting a subrate binary data stream into a binary signal at the line transmission rate comprises means for periodically accepting a date byte from the subrate data stream and; means for expanding the data byte by one additional bit by adding a control bit in the first bit position of the accepting means. The apparatus additionally comprises means for recirculating the expanded data byte through the accepting means a predetermined number of times and means for serially reading out bits of the expanded data byte at the line transmission rate.
